Explainer: The US push to boost 'quantum computing'

A race by U.S. tech companies to build a new generation of powerful "quantum computers" could get a $1.3 billion boost from Congress, fueled in part by lawmakers' fear of growing competition from China.

Legislation passed earlier in September by the U.S. House of Representatives would create a 10-year federal program to accelerate research and development of the esoteric technology. As the bill moves to the Senate, where it also has bipartisan support, the White House is showing enthusiasm for the effort with a planned quantum summit on Monday.

Scientists hope government backing will help attract a broader group of engineers and entrepreneurs to their nascent field. The goal is to be less like the cloistered Manhattan Project physicists who developed the first atomic bombs and more like the wave of tinkerers and programmers who built thriving industries around the personal computer, the internet and smartphone apps.
